Beyond Push-Button GPS
In 1993, the U.S. Air Force Space Command will complete its deployment of 24 satellites for the Global Positioning System, affording 3-dimensional positions and velocities 24 hours a day...

Analysis of a Wharf for a Container Terminal
A balanced combination of sophisticated computer programs was employed to model the soil strata, foundation and structure of a wharf for a new container terminal in the Port of Topolobampo,...

Application of Traffic Engineering Concepts to Pleasure Boat Traffic
The Los Angeles County Department of Beaches and Harbors initiated a study to investigate the feasibility of adding slips along the main channel in Marina del Rey in response to the surplus...

Case Study ? Elliott Bay Marina Floating Moorage
The recently completed Elliott Bay Marina project in Seattle is one of the larger projects of this type in the country, with 1196 slips ranging from 32 feet to 60 feet, a floating fuel...

Non-Intrusive Rayleigh Wave Measurement System for Soil Profiling in Ports
Accurate shear wave velocity profiles have been long recognized as essential data to evaluate the dynamic response of soil deposits and soil-structure interaction under earthquake and...

Analysis of Dredged Material Deposition Patterns
Between November 1, 1989 and 30 March, 1990, nearly 1 million cubic yards of dredged material were disposed in Puget Sound as the first phase (Element I) of the construction of the Navy's...

Results of a Monitoring Program of Moored Ship Response to Gravity and Infragravity Waves
An automated monitoring system was designed and operated at a coal terminal in Los Angeles Harbor, and a container terminal in Long Beach Harbor, to obtain the complete six degree-of-freedom...

Floating or Fixed Dock for RO/RO Ship Operations
Floating pontoon-type dock structures are typically used for RO/RO ship berthing. Primary advantage of a floating dock for RO/RO berthing is the relatively constant height relationship...

Evaluation of Proposed Port Facilities, Charleston Harbor, South Carolina
Often it is necessary for port facility designers to evaluate various alternative development plans for port facilities. These evaluations may include a ship navigability study or an evaluation...

Predicting Water Demand in Agricultural Regions Using Time Series Forecasts of Reference Crop Evapotranspiration
Overall, it can be said that the time series model developed in this study did provide superior forecasting results for the Brawley, CA, site. This indicates that the monthly reference...

Streamflow Forecasting Using Trainable Neural Networks
In this investigation the practicality of applying a backpropagation neural network to modeling watershed response characteristics is examined. Two separate tests were performed. One test...

Spatial Decision Support System for Toxic Spill Modeling in the Ohio River
Spatial decision support systems (SDSS) are hardware-software systems that incorporate spatial analysis and modeling in a workstation environment. The Ohio River Valley Water Sanitation...

An Approach for Incorporating Inflows Uncertainty in Management Models
Inflow uncertainty is probably the most difficult issue for optimal management of conjunctive use water resources systems. In many instances, the effect of future inflows and their uncertainty...

Computer-Aided Support for Water Quality Modeling of the Russian River
A computer-aided support system for operation of the QUAL2E-UNCAS modeling packaged has been developed for modeling of the Russian River, California. The system has been created under...

Development of the San Fernando Basin Groundwater Flow Model
This paper describes the development and calibration of the San Fernando Basin (SFB) groundwater flow model. The SFB is the largest groundwater basin in the Upper Los Angeles River Area...

Hydrologic Investigation of the April, 1983 Flooding in New Orleans, Louisiana
During the rainstorm of April 6-7, 1983, a shell ramp was constructed over State Highway 406, closing the relatively shallow depression formed by the roadway passing over the levee which...

Assessment of Derived Flood Frequency Distributions
Derived flood frequency distributions based on the geomorphologic IUH are evaluated in this work. Two existing approaches, the methods of Hebson and Wood (1982) and Diaz-Granados et al....

Dry Creek Watershed Flood Control Plan: A Case Study
This paper describes the development of the Dry Creek Watershed Flood Control Plan. This study was conducted to quantify the extent of the existing and future (buildout) drainage problems...

Optimization Model for Operation of Recharge Basins
A mathematical model is developed for the optimal operation of recharge basins, which is a non-linear optimization problem. The objective of the model is to determine the operation that...

Computer Modeling Responsibilities for Municipalities
Municipal organizations are often faced with a complex set of water resource problems which can best be analyzed through the use of computer models. The development of such models can...
